San Diego County, San Diego Rat Control Situation:
Hi David, Is a UV blacklight still useful, exterior-wise, if it rains after the rodents leave their urine stains? I am in the process of performing exterior maintenance to better exclude my roof rats. 1) I have a 25 year old cedar shake roof in San Diego California with openings under each shake along the rake edge of the roof at the gable ends of my house. There's no drip edge, i.e. under the shakes I have roofing paper (now somewhat curled) that runs more or less up to and rests right atop the fascia board. Because I have skip sheathing, and since the cross section of a shake is a wedge that is up to one inch at the upper, thick end, this appears to create many huge entry points along the rake edges even though the sheathing is rabbeted into the fascia board. As a result, I'm thinking of getting a UV blacklight to use outside the house to sleuth for urine stains along the upper edge of the gable end shakes and fascia boards. My question is, how easily does the winter rain wash away the urine, rendering this a pointless exercise? 2) I noticed a new product called "rat-out gel" and was thinking of applying it along the rake edges mentioned above. Or, maybe I should just buy many rolls of X-Clude and use that instead. Or maybe both. Any comment? Thanks very much for your website, Doug
My response: First off, I do not have experience using UV lights to detect rat urine. But I do suspect that rain will severely limit the effectiveness of this approach. I have never heard of Rat-Out Gel or XClude, but I typically stick to physical barriers rather than repellent type devices. If your roof makes this impossible, you might have a tough time keeping the rats out.

The Proper Way To Clean Rat Feces Out Of Your Attic
If you already know the dangers of having rat feces in your attic and coming in contact with it, you are most likely going to get scared and confused about how to clean it. When it comes to cleaning rat feces, you can't afford to do it the wrong way. Refusal to follow the due process might cost you more of what you are trying to prevent.
Since rat feces is a major carrier of bacteria and other disease-causing organisms, the first thing you need to do when planning to clean out the feces from your attic is to protect yourself appropriately. To do this, you need to start by ventilating your attic for as long as possible before entering. By doing this, you are simply expelling the contaminated air and allowing fresh air to go in. This protects you from breathing air that is contaminated with rat feces while in the attic. Also, you need to have equipment such as a facial mask, gloves, plastic bags, and a strong disinfectant in place before going ahead to clean your attic.
Just like every other part of your home, cleaning your attic is not that difficult. Provided you have all the supplies listed above, you will find it quite easy to do. To start, wear your facial mask and gloves properly and carefully pack the feces into the plastic bag. After that, dispose of the plastic bag safely.
When you are done with that, you need to soak the floor of your attic with a disinfectant and then scrub the floor until all the remaining feces are removed. Leave the disinfectant on the floor for 10 minutes to allow it to kill all the pathogens and bacteria deposited by the rat. After doing all this, your attic will be completely pathogen and bacteria-free.
If you find any of these is difficult to do, you can hire a professional to help you out with the cleaning.
